Could some answer these questions please? I'm a newbie.1. How do you run a program in the 'background'?2. If you have something in the background, how do you bring it forward? Do you send it back to background the same way?3. I guess background is a 'process'. Are there more? What would they be called so I can learn more about them?4. What is something called 'granddaddy' process? Sound weird...lol.
